Question: 1 / 1505

Every _________ township line above a baseline is known as a correction line.

second

third

fourth

In the context of the Public Land Survey System (PLSS), a correction line is established to adjust for the curvature of the Earth. Specifically, every fourth township line above a baseline is designated as a correction line. This system is crucial for maintaining accurate land measurements, as the Earth is not a flat surface and consequently, the townships do not fit perfectly into the grid layout due to the convergence of meridians.

The correction lines are placed to ensure that the township section divisions remain consistent with the intended six-mile spacing of township lines. This means that as you move north of a baseline, after every third township line, a fourth line is used to correct the potential discrepancies caused by the Earth's curvature. Understanding the significance of correction lines helps in grasping how land is surveyed and divided in this system.
